<P>PROBLEM TO BE SOLVED: To provide a maintenance support device for plant equipment, accurately estimating an influence degree of abnormality of the plant equipment upon plant operation even without relation to aging degradation, and deciding inspection technique/time of the equipment. <P>SOLUTION: This maintenance support device comprises: an observation value database 1 of the plant equipment; an equipment database 2; an inspection information database 3; a state diagnostic part 4 diagnosing the plant equipment abnormality at arbitrary time by use of information and an observation value thereof; a plant operation influence degree estimation part 5 estimating influence of the plant equipment abnormality upon the plant operation by use of the equipment information, inspection information and information from the state diagnostic part; and an inspection method/time decision part 6 deciding the inspection method/time of the plant equipment on the basis of a result obtained by the state diagnostic part 4 and the plant operation influence degree estimation part 5. The state diagnostic part 4 includes a model production means, a model calculation means and an abnormality probability calculation means. Abnormality probability of the equipment at the arbitrary time is calculated, the influence degree upon the plant operation when the equipment comes into the abnormality is estimated, and the inspection method/time of the equipment is decided. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
